Two similar entity properties generated in runtime/cache/cycle.php

[anlamas]

If u manually specify name of inner key in a relation

/**
* @Cycle\Column(type="bigPrimary")
*/
protected int $id;

/**
* @Cycle\Column(type="bigInteger", nullable=true)
*/
private ?int $parentId;

/**
* @Cycle\Relation\BelongsTo(target="ProductCategory", innerKey="parent_id", nullable=true, fkAction="SET NULL")
*/
private ?ProductCategory $parent;

You get this

'id' => 'id',
'parentId' => 'parent_id',
'parent_id' => 'parent_id',

Expected result

'id' => 'id',
'parentId' => 'parent_id',

The documentation says:

innerKey -- Inner key in source entity. Defaults to {relationName}_{outerKey}

Therefore, for your case it will be more correct like this:

/**
* @Cycle\Relation\BelongsTo(target="ProductCategory", innerKey="parentId", nullable=true, fkAction="SET NULL")
*/
private ?ProductCategory $parent;

But be careful: in your example, the settings for the $parentId field will be different from those implied for the BelongsTo relation. Among other things, the BelongsTo relaction sets the default value to NULL for the innerKey field.
